2010 Annual Report


4.Accomplishments
1. Rubber reinforcement with modified corn flour. To contribute to the sustainability of materials we use today, development of different economical alternatives is required. PPL Unit scientist at National Center for Agricultural Utilization Research in Peoria,IL, developed a method using gelatinized and shear-degraded corn flour mixed with rubber emulsion and then melt-processed. The resulting material has better mechanical properties for rubber applications than untreated corn flour. This accomplishment will impact the technology of rubber composite applications by providing reinforcing fillers based on renewable agricultural materials instead of petroleum/natural gas derived fillers.

2. Rubber reinforcement with corn starch/biochar. To optimize the economical value and application properties of bio-fillers, PPL Unit scientist at National Center for Agricultural Utilization Research in Peoria,IL, used corn starch and biochar together as co-fillers to enhance the mechanical properties of the rubber material. The resulting rubber composites with a certain ratio of starch/biochar have some mechanical properties that are comparable to those of carbon black-filled composites. This accomplishment will impact the technology of rubber composite applications by providing reinforcing fillers based on renewable agricultural materials instead of petroleum/natural gas derived fillers.
